I was thinking that it would be interesting if a traitor could call forth the Innocents win popup box as a skill thereby rendering remainign players complacent while they go in for a final kill.
Examples of uses:
3 players remain, one is killed, the traitor immediately uses the skill to allow his nearby comrade to think he is safe, then immediately goes in for the kill b/c the game is no longer supposedly on the line.
I'm sure you can think of many other interesting uses. Let me know
